I would like to ask whether a dihydrogen peroxide storage tank should be equipped with a cofferdam or a fire dike Urgent urgent urgent
Thread Content
Hydrogen peroxide storage tank, 1 unit: φ2.76×3.68m, VN=20m, at normal temperature of 27°C. 5% salt, acid, and liquid alkali storage tanks are located in the same tank area. Should hydrogen peroxide be used to create a dike or a fire barrier? Does the volume of such a dike need to be 20 m3, equivalent to the total effective volume of all the storage tanks?
I also want to ask what distance should be maintained between the hydrogen peroxide storage tank and the storage tanks for acid or liquid alkali? What should be the distance between the acid salt tank and the acid salt or liquid alkali tank?

It should be to build a fire dike! Isn’t it required now to have one tank per dike?
The alkali storage tanks and acid-salt storage tanks I’ve seen do not use floodwalls; instead, they have dikes that are only 20 cm above the ground level. The key issue is that there must be a drainage system inside these dikes. The same should be true for hydrogen peroxide.
Hydrogen peroxide is a strong oxidizing agent, classified as Category A in terms of fire hazard, and fire dikes should be installed in accordance with building codes.
Our factory’s hydrogen peroxide storage tanks are equipped with cofferdams
What we are building are firebreaks; the exact distance hasn’t been measured, but there must be a standard, and the construction workers surely know it. Hope this can help you
A hydrogen peroxide storage tank was classified as Category A according to the flammable oxidizer classification system, based on its fire hazard category. Class A storage tanks require fire dikes, and the spacing should be determined in accordance with sections 4.1–4.2 of the building codes
Sir, when the proportion of area occupied by equipment with the highest fire hazard category is less than 5%, and in the event of an accident, the fire cannot spread to other areas or the spread of fire can be prevented through fire prevention measures, it can be classified according to the equipment with a lower fire hazard category. Does a hydrogen peroxide storage tank also need a fire dike? Can a cofferdam be built?
What you’re referring to is the factory building or its fire compartments, not the storage tanks
